More isn't always better: Too much calcium has risks. Dietary calcium is generally safe, but more isn't necessarily better, and excessive calcium doesn't provide extra bone protection. If you take calcium supplements and eat calcium-fortified foods, you may be getting more calcium than you realize.
Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation.
Transduction. 1  Another method of genetic transfer and recombination is transduction. 2  This method involves the transfer of DNA from one bacterium to another with the use of a bacteriophage (phage). 3  A phage is a virus that infects bacteria. 4  The phage T4 and the phage lambda, for example, both infect E. coli.
